목적: 상완골 근위부 골절에 대하여 최소 침습적 금속판 술식을 시행하고, 임상 결과를 분석하여 유용성을 알아보고자 하였다. 대상 및 방법: 상완골 근위부 골절에 대하여 최소 침습적 금속판 술식을 시행한 27명을 대상으로 하였다. 골절 분류는 2분 골절 16예, 3분 골절 10예였으며, 4분 골절 1예가 포함되었다. 임상적 평가는 UCLA 점수와 KSS 점수 및 운동 범위 회복 정도와 합병증 발생 여부를 조사하였으며, 방사선학적으로는 골유합 기간과 경간각 회복 정도를 평가하였다. 평균 추시 기간은 19개월이었다. 결과: 최종 추시에서 UCLA 점수는 우수가 15예, 양호가 12예였으며 KSS 점수는 평균 91.4점이었다. 또한 최종 견관절 운동 범위는 전방 거상이 평균 167.2º로 측정되었다. 모든 환자에서 수술 후 평균 14.1주에 골유합을 얻었으며, 경간각 회복 정도는 우수가 24예였으며 보통이 3예였다. 액와 신경 마비나 심부 감염, 금속판의 충돌 증후군 등의 합병증은 발생하지 않았다. 결론: 상완골 근위부 골절에 대한 최소 침습적 금속판 술식은 충분한 해부학적 지식을 숙지하고 시행하면 주변 연부 조직 박리를 최소화하여 합병증 발생을 감소시키고 조기 관절 운동을 가능하게 하므로 상완골 근위부 골절 치료의 효과적인 수술 방법의 하나로 사료된다. Purpose: In this study we introduced minimal invasive plate osteosynthesis (MIPO) and analyzed clinical outcomes to determine the effectiveness of this intervention in proximal humerus fractures. Materials and Methods: We studied 27 patients including 16 cases with a 2-part fracture, 10 cases with a 3-part fracture, and 1 case with a 4-part fracture. Clinical outcomes were evaluated using UCLA score, KSS score and recovery of range of motion. Time to union and humerus neck-shaft angle change were estimated by radiologic assessment. The average follow up period was 19 months. Results: UCLA scores were “excellent” for 15 patients, “good” for 12 patients. The mean KSS score was 91.4 at final follow-up. The average shoulder range of motion was 167.2º in forward elevation. Bone union occurred by 14.1 weeks postoperatively. Humerus neck-shaft angle recovery was “excellent” in 24 patients and “moderate” in 3 patients. There were no complications such as axillary nerve paralysis, deep infection, or subacromial impingement of the plate. Conclusion: MIPO for proximal humerus fractures is an effective procedure if performed with sufficient understanding of the anatomical structures. MIPO leads to minimized dissection of soft tissue, low complication rates and early recovery of range of motion.

Tantalum 망상 금속 대치술을 이용한 대퇴 골두 무혈성 괴사 치료의 초기 결과
김종오 ( Jong Oh Kim ),노권재 ( Kwon Jae Noh ),박현식 ( Hyun Sik Park ),도남훈 ( Nam Hoon Do ),김태호 ( Tae Ho Kim ),손훈상 ( Hun Sang Son ) 대한고관절학회 2009 Hip and Pelvis Vol.21 No.2
Purpose: To evaluate the effectiveness of core decompression using a tantalum trabecular metal system for treatment of early stage osteonecrosis of the femoral head, with a minimum follow-up of 1 year and a maximum follow-up of 5 years. Materials and Methods: Between January 2003 and August 2007, a retrospective analysis was conducted on 46 femoral heads in 36 patients (9 males and 27 females) underwent core decompression using a tantalum trabecular metal system. The mean duration of follow-up was 26 months (minimum, 1 year; maximum, 5 years). The ARCO classification system was used. The mean age of the patients was 42.9 years. The conversion to total hip arthroplasty due to aggravating hip pain was defined as a clinical failure. Results: At an average of 12 months, 18 patients (21 hips) were converted to THR. No conversion to THR in occurred in stages IA or IIA. In Stage IB, one-half of the medial lesion and all of the lateral lesions were converted to THR. One of 11 medial lesions and all of the lateral lesions in stage IC were converted to THR; 2 of 3 medial lesions and all of the lateral lesions in stage IIB were converted to THR. In stage IIC, 6 of 8 lateral lesions were converted to THR, but the central lesions were not converted. All of the lateral lesions in stage IIIC were converted to THR. Conclusion: The higher stage of ARCO classification and the more lateral position of the lesion, the greater the failure rate of the tantalum trabecular metal system. Conversion to THR from a failed tantalum trabecular system developed within 12 months postoperatively. The tantalum trabecular metal system is a useful treatment for osteonecrosis of the femoral head with a lower stage of ARCO classification and a medial location of the lesion.
